Deciding whether to stay in or leave a relationship ranks among life’s most difficult choices. Neither staying in an unhealthy relationship nor leaving a salvageable one serves your wellbeing. Dr. John Gottman’s research identifies specific patterns that predict whether relationships can improve or are fundamentally incompatible (Gottman, 1999).

Clear Signs You Should Leave

Some situations require leaving for your safety and wellbeing, regardless of other factors:

Physical Violence or Abuse

Any physical violence—hitting, shoving, restraining, or threatening with weapons—requires immediate departure. Physical abuse escalates over time and doesn’t improve without intensive professional intervention that occurs separate from the relationship.

Emotional or Psychological Abuse

Systematic patterns of manipulation, gaslighting, isolation, verbal attacks, or control require leaving. Emotional abuse causes lasting psychological damage and rarely improves even with therapy.

Active Addiction Without Treatment

If your partner has active addiction and refuses treatment despite how it’s affecting the relationship, leaving protects you from enabling and from the chaos addiction creates. You can love someone and still recognize you can’t save them.

Repeated Infidelity

While single instances of infidelity can be worked through, repeated betrayals despite promises to change indicate fundamental unwillingness to maintain relationship boundaries.

Fundamental Incompatibility

When core values, life goals, or non-negotiable needs are incompatible—one wants children and the other doesn’t, irreconcilable religious differences, completely different lifestyle preferences—no amount of love creates compatibility.

Signs the Relationship Is Worth Saving

Other situations indicate the relationship has potential despite current difficulties:

Both Partners Are Committed to Change

When both people acknowledge problems and actively work on improvement through therapy, reading, or implementing changes, the relationship has potential.

Problems Are Situational, Not Fundamental

External stressors—job loss, illness, family crisis—are creating relationship strain. Once the stressor resolves or you develop better coping strategies, the relationship can improve.

You Have Positive History to Build On

The relationship once was healthy and satisfying. You remember why you fell in love, and those qualities haven’t fundamentally changed—you’ve just lost connection temporarily.

There’s Still Affection and Respect

Despite problems, you still care about each other, want the other’s happiness, and treat each other with basic respect. Contempt and disgust haven’t replaced love.

You’re Willing to Do the Work

Both partners are willing to attend therapy, have difficult conversations, make personal changes, and invest time and energy in improvement.

The Gray Area—When It’s Unclear

Most relationships fall in the ambiguous middle where the decision isn’t obvious:

Questions to Ask Yourself

Does this relationship bring more joy than pain? Healthy relationships have conflicts but overall feel good. If the relationship feels predominantly negative, that’s a warning sign.

Am I staying out of love or fear? Fear of being alone, financial concerns, or worry about partner’s reaction to leaving are different from genuine love and commitment.

Have I tried everything reasonable to fix this? Have you communicated clearly, attended therapy, implemented changes, and given adequate time for improvement?

Would I want a friend or child in this relationship? If you’d advise a loved one to leave a relationship like yours, that perspective matters.

Am I growing or shrinking in this relationship? Healthy relationships support growth. Unhealthy ones diminish you over time.

Can I envision a happy future together? If you can’t imagine genuine happiness together even with improvements, that’s telling.

The Trial Separation Option

When decision feels impossible, structured separation provides clarity:

Define the Separation Terms

• How long will it last (typically 3-6 months)?
• Will you see each other? How often?
• Are you dating other people or exclusive?
• What are you each working on individually?
• What would need to change for reconciliation?

Use the Time Productively

• Attend individual therapy to gain clarity
• Work on personal growth and healing
• Miss your partner or realize you feel relief?
• Notice what you appreciate or what you don’t miss
• Imagine future with and without your partner

Making the Final Decision

If Staying:

Commit fully rather than staying ambivalently. Half-in relationships create perpetual dissatisfaction. If you’re staying, invest in making it work.

Create clear action plan for improvement with specific goals, timelines, and therapy if needed.

Accept your choice without resentment. You’re staying because the relationship has value worth fighting for, not because you’re trapped.

If Leaving:

Make the decision clearly and communicate it directly. Don’t threaten to leave as manipulation—decide and follow through.

Plan logistically before announcing the decision—where you’ll live, financial arrangements, custody if children involved.

Expect grief even when leaving was right choice. You can mourn the relationship while knowing leaving was necessary.

Create support system to help you through the transition—friends, family, therapy.

The Sunk Cost Fallacy

Don’t stay just because you’ve already invested years. Time already spent doesn’t obligate you to spend more time unhappily. The question is whether the relationship serves your future, not whether leaving “wastes” your past.

Considering Children

Children complicate but don’t necessarily change the calculation:

Staying “for the kids” often backfires. Children raised in high-conflict homes have worse outcomes than children of divorced parents who co-parent respectfully.

However, if the relationship is salvageable and both parents are committed to improvement, working on the relationship models perseverance and problem-solving for children.

The key: Don’t stay in genuinely unhealthy relationships “for the children,” but don’t give up on fixable problems just because divorce feels easier.

Professional Support for Decision-Making

Too Good to Leave, Too Bad to Stay by Mira Kirshenbaum provides diagnostic questions to help you determine whether your relationship has potential or whether leaving serves your wellbeing better.

Conclusion

Deciding whether to stay or leave a relationship requires honest assessment of whether the relationship serves your wellbeing, whether both partners are committed to improvement, and whether fundamental compatibility exists. There’s no shame in leaving relationships that can’t be healthy, and there’s no weakness in fighting for relationships that have genuine potential. Trust yourself to make the decision that honors both your worth and your values. Sometimes love isn’t enough, and sometimes love combined with work is everything you need.
